Description Creates a RAID level 10, 50, or 60 (spanned) configuration from the specified drive
groups. Even if no configuration is present, you must use this option to write the
configuration to the controller.
Note that RAID 10 supports up to eight spans with a maximum of 32 drives in each
span. (There are factors, such as the type of controller, that limit the number of drives
you can use.) RAID 10 requires an even number of drives, as data from one drive is
mirrored to the other drive in each RAID 1 drive group. You can have an even or odd
number of spans.
Multiple drive groups are specified using the
–ArrayX[E0:S0,...]
option. (Note that
X starts from 0, not 1.) All of the drive groups must have the same number of drives.
At least two drive groups must be provided. The order of options
{WT |WB} {NORA
| RA | ADRA} {Direct | Cached}
is flexible.
The size option,
-szXXXXXXXX,
can be accepted to allow slicing in the spanned drive
groups if the controller supports this feature. The
[–afterLdX]
option is accepted if
the size option is accepted. CT exits and does not create a configuration if the size
or the afterLd option is specified but the controller does not support slicing in the
spanned drive groups.
1. NOTE: Previously
-szXXX
expressed capacity in Mbytes but now you can enter
the capacity in your choice of units. For example, to create a virtual drive of 10
Gbytes, enter the size as sz10GB. If you do not enter a unit, by default it is con-
sidered as Mbytes.
